# Step 5-8

{% hint style="success" %}
Vibra-TITE VC-3 Threadmate ([Vibra-TITE](https://wcproducts.com/products/threadlocker)) is recommended on all bolts that thread into a tapped hole.
{% endhint %}

## Step 5

Press the 72T Rotation Gear in by hand. If necessary, use a dead blow hammer to lightly tap it in. 

The Wheel Module Drive Shaft must be installed through the bottom side of the 3/8” Rounded Hex bearing.

| Gear Ratio Kit | 2nd Stage Driven Gear |
| -------------- | --------------------- |
| X1             | 20t                   |
| X2             | 18t                   |
| X3             | 18t                   |

{% hint style="info" %}
The Wheel Module Drive Shaft was updated to get rid of the #8-32 bolt and printed cap. If your shaft has a tapped hole, refer to the v1 Drive Shaft image below. If your shaft doesn't have a tapped hole, refer to the v2 Drive Shaft image below. 
{% endhint %}

## Step 6

The 1/4” ID x 5/8” OD bearing can be pressed into the Wheel Module Fork by hand. Only the Fork that aligns with the Wheel Module Drive Shaft needs a bearing. Once the bearing is in place, use the #10-32 x 1 3/4”L bolts to install both forks into the module.

{% hint style="info" %}
If you ordered your Wheel Module Forks after 5/16/2023, make sure an updated Wheel Module Fork is used on the side with the 15T Bevel Gear. The updated Wheel Module Fork will have a pocket designed to fit a 1/4-20 Nut machined into the outside face.

## Step 7

The Main Drive Shaft and corresponding gear should be installed before the 3D Printed Rotation Pulley. Use the #4-40 x 7/8”L bolts to install the 3D Printed Rotation Pulley.

| Gear Ratio Kit | 2nd Stage Driving Gear |
| -------------- | ---------------------- |
| X1             | 26t                    |
| X2             | 28t                    |
| X3             | 28t                    |

{% hint style="info" %}
The 3D Printed Rotation Pulley was updated to strengthen the part and allow for longer bolts. If your 3D Printed Rotation Pulley does not have a step at the bottom of the integrated spacers that nests in the 72T Main Rotation Gear, then install the pulley using #4-40 x 3/4"L bolts.
{% endhint %}

{% hint style="warning" %}
Do NOT overtighten the #4-40 bolts, as this will crush the 3d printed part.
{% endhint %}

## Step 8

For the Non-Flipped configuration, the output shafts for the motors must be shortened for clearance. If you do not want to cut the shafts, we recommend installing the Motor Spacers.&#x20;

For all configurations, the motors are installed using #10-32 x 1/2”L bolts. The pinions are bolted in using #10-32 x 1/2”L bolts.

{% hint style="info" %}
For the Drive Pinion refer back to the [Ratio Options](/welcome/gearboxes/wcp-swerve-x/general-info/ratio-options.md) page.
{% endhint %}

{% hint style="warning" %}
When using the X3 Ratio Set for the Standard Configuration, the Drive Pinions on a 14T CD will collide with the Top Plate.&#x20;

To prevent this, the options are:&#x20;

**1) (Recommended)** The pinion can be cut shorter by a 1/16" and spaced down to the end of the motor shaft.&#x20;

or

**2)** The hole can be drilled to 0.875" to provide necessary clearance for pinion.
